Improving the working conditions for refineries

As the world’s leading producer of thiochemicals, Arkema’s manufacturing expertise assures the highest and the most stable purity DMDS. Our DMDS Evolution® E2 is a breakthrough formulation for a better smelling DMDS sulfiding agent. It outperforms in odor control, providing a more pleasant fragrance, and improving the user working condition

Reducing sulfur emissions in the air

Leveraging its expertise in handling H2S, Arkema has developed Carelflex®, an on-site sulfiding service for refineries, carried out by highly qualified technicians, in order to provide a real-time, and accurate H2S measurement tool during HDP catalyst activation. By using, only the appropriate amount of DMDS, our Carelflex® service makes it possible to lower the sulfur emissions in the air often considered as major source of acid rain, thus preserving aquatic life.

Optimizing the catalyst consumption for steamcrackers

By delaying coke formation in the steamcrackers furnace coils, DMDS contributes to extend the furnace running cycles and optimize the production capacities and yields with a responsible energy consumption. DMDS is also the sulfiding agent that provides the highest activity to your hydrotreatment catalysts, enabling to reduces the catalyst consumption and to run at lower temperature for the same performances.

 

 

Digitalization for real-time telemetry & communication for refineries

Arkema offers Carelflex®, an on-site sulfiding service carried out by highly qualified technicians, providing the technical and safety knowledge, as well as assistance you need for efficient, hassle-free catalyst sulfiding. Taking a step forward, Arkema innovates with a digital interface that eases live communication between the refinery control room and the Carelflex® team during sulfiding. The extensive monitoring that companions the Carelflex® digitalized skids enables better anticipation of potential issues, improves operation safety to achieve the highest catalyst activation and resume production on time.

Improving the steamcrackers production efficiency

Hydrocarbons exposed to elevated temperatures form coke, which can cause metal carburization and affect heat transfer and flow dynamics. In less than 15 minutes, enough coke is formed to require PDH and BDH unit shutdown and immediate cleaning and decoking. DMDS Evolution® E2 is the leading sulfur-based, coke suppression and metallurgy protection technology
